A dirty air filter can have a significant impact on engine performance. When the air filter is clogged, it restricts the amount of air that can enter the engine, leading to a decrease in fuel efficiency and an increase in unburned fuel. This unburned fuel forms a soot residue that accumulates in the spark plug, causing it to become fouled and unable to produce the spark needed for combustion. As a result, the car may experience decreased performance and even engine damage.
To prevent this from happening, automotive experts recommend replacing the air filters every 12,000 miles or 12 months, depending on driving habits. In addition to replacing the air filter regularly, using a reusable air filter such as a K&N filter can help improve engine performance and fuel efficiency. These filters are designed to be cleaned and reused over and over again, providing optimal performance for the entire life of your vehicle. However, it is important to note that the inner layers of filter paper inside the air cleaner may have no visible debris or dust and dirt, even in bright light.
Therefore, it is important to consult your owner's manual for details of your vehicle's air filter replacement program. In conclusion, a dirty air filter can have serious consequences for engine performance. To ensure safe and optimal performance of your engine, make sure to address dirty air filter symptoms immediately and always have a clean air filter in place. Additionally, using a reusable air filter such as a K&N filter can help improve engine performance and fuel efficiency.
